Abstract

The nozzle comprises a head with an inlet and one or more outlets, each containing a diffuser (4) in the form of a bush (5) with a conical inner cavity containing a conical component (6), and an outlet (8). The conical component has three spiral grooves (14a, 14b, 14c) with their ends at the base of the cone connecting with the interior of the diffuser via separate orifices (15a) at an angle of 120 degrees to one another, and at the tip of the cone meeting a common outlet (8). The inner surface of the bush and outer surface of the cone have matching threads for screwing together.
